Concussion & Mild traumatic brain injury

Concussions are the result of acceleration-deceleration forces applied to the brain, and are a common occurrence in contact sports or sports involving speed. Concussion may result from direct impact or sudden rotational or shear forces transmitted to the brain, causing axon (nerve) dysfunction. A number of neurological functions may have been affected and symptoms can vary considerably, therefore a thorough evaluation should be conducted by a medical professional.

results in a graded set of clinical symptoms that may or may not involve loss of consciousness. Resolution of clinical and cognitive signs typically follow sequential course, however in a small percentage post-concussive symptoms may be prolonged

no abnormality on standard structural neuro-imaging studies are seen in concussion.

Symptoms

The diagnosis of acute concussion involves the assessment of a range of domains, which include clinical symptoms, physical signs, behavior, balance, sleep and cognition. A detailed concussion history is also an important part of the evaluation. The suspected diagnosis of concussion may include one or more of the following clinical domains:

clinical symptoms such as headache, feeling like in a fog, emotional instability, attentional deficits or altered mental status and visual disturbances

If any one or more of these symptoms are present, a concussion should be suspected and the appropriate assessment and management strategy should be instituted by a qualified medical professional. The player should not be left alone following the injury and serial monitoring for deterioration is essential over the initial few hours following concussion. It is not uncommon for symptoms to be delayed several hours following a concussive episode, and it is essential that worsening symptoms prompt immediate referral to a hospital.

Treatment often involves vestibular rehabilitation (balance and postural stability, eye and head control) exercises as these sensitive sensory systems, which are managed by the brain, are often affected. Treatment will also likely involve the neck.

Return to Play

A player with a diagnosed concussion should be evaluated before return to play with a structured physical and cognitive assessment, as there is a substantial risk for further deterioration or injury with trauma or exertion when symptoms have not fully resolved. Helmets and mouth guards continue to be recommended to protect against head and facial injuries, and may reduce the incidence and/or severity of concussions.
